How do I install patches?
The simple answer is that you don't.

These patches are not intended for the end-user. They are intended to be used by developers to modify the source-code of Blender.

If you feel that you've got the skill-set to modify the source-code, more power to you! Unfortunately, most of us won't be much help. You'll get better support from the developers over at the Blender development project.
